This proposed law would (1) prohibit the Massachusetts Gaming Commission from issuing any license for a casino or other gaming establishment with table games and slot machines, or any license for a gaming establishment with slot machines; (2) prohibit any such casino or slots gaming under any such licenses that the Commission might have issued before the proposed law took effect; and (3) prohibit wagering on the simulcasting of live greyhound races. The proposed law would change the definition of "illegal gaming" under Massachusetts law to include wagering on the simulcasting of live greyhound races, as well as table games and slot machines at Commission-licensed casinos, and slot machines at other Commission-licensed gaming establishments. This would make those types of gaming subject to existing state laws providing criminal penalties for, or otherwise regulating or prohibiting, activities involving illegal gaming. The proposed law states that if any of its parts were declared invalid, the other parts would stay in effect.
